I'm using fullCalendar with Oracle APEX. By default when the window resizes (around 715px) the View mode automatically changes to List View. I want to keep the same view unless the user clicks on the List view.
How can I prevent the automatic view change on WindowResize?

I am trying to develop a mobile application using flex. Whenever I use 'navigator.popView()' to go back to the last view that was shown, it loads a new view on to the screen, instead of using the old one itself.
On the first screen, I have a TextInput into which I enter some text, when I push next and then push back the TextInput is empty. I want to retain the text in the TextInput.
It is advisable not to keep views in memory by default, so discarding old views and creating new ones is really the desired behavior. You should bind the content of your TextInput to a variable and store and retrieve only its text value.
I'm working on a flex 4.6 mobile project
and I found TabbedViewNavigatorApplication will destory the old view and create a new view every time change a tab.
For example, user entered some text at a textInput in View1, then user change to View2 tab and change back to View1 tab. at this time, the entered text is gone.
My question is
How to keep these view instance when changing tabs(just like iphone tabbar did)?
Did you try destructionPolicy="never"property in View component?
Functionnaly :
On one of my components of my application, I have an editing/lock system. When a user starts editing, he locks the file so other users cannot edit it.
Problem scenario : When the user activates "edition mode" and leaves screen, I would like to show a alert with two options : save changes, or discard changes.
There are different ways to exit screen :
There is a List on the left side containing other possible editabel data. A click changes the data in my component.
There is a menubar on top leading to other screens.
The edition component is embedded in a Tab navigator. When changing tabs, the alert has to show.
Closing browser.
Do I have to catch all of these events and plug at all those places?
Is there any kind of focusout mecanism?
The answer to the first question is: YES.
You need to watch all possible exit events that could harm the currently edited data.
Well, the problem is now how to manage this properly. Using an MVC framework you would trigger the appropriate commands from your components:
CHANGE_LIST_ITEM (new item)
CHANGE_TAB (new tab)
CHANGE_SCREEN (new screen)
Each command then checks if the currently edited tab has been saved or not. If not, it displays the Alert. Else, if there are no changes, it allows the list, the screen chooser and the tab bar to continue.
So your components (list, screens, tabs) need to implement some kind of rollback or preventDefault mechanism. Generally, changing their state must be allowed by a central validator (in MVC the command).
In the case of the list: I would suggest that the list is not selectable by mouse click but only programmatically. You set a listener on the list item click event. If the command allows setting of a new item it will notify the list. In MVC usually by sending an async message that gets received by the list's mediator. [[And even more correct: The command would set some model properties (e.g. currentListItem) and the model than sends an async message.]]
Edit: For the browser close event, you need to call a JavaScript expert.
I have an AdvancedDataGrid. One of the columns in the grid displayed with help of custom render. During the application run, I set another custom render to the same column. When I scroll data in the grid (change values for the custom renders) they display new view correctly.
I want that they dispaly new view automatically (when I set them): so I think I have to call them and tell tham to refresh rgeir views. Any idea how to do this?
Use invalidateList()
I have one .mxml file (the Application) with a ViewStack (with 4 views) and a ControlBard, obviously I can change the views with it, but what I want to do is: in view #1 I have an image which I want to convert to a "hyperlink", so when I click it I go to View #2, is this doable? Also I would like to pass somehow some data (like a String) to that View #2 (lets say the it's a user avatar I click so I want to go to the second view which will show me his profile, that's why I need his name/id).
One way, loosely coupling, Create a custom event (SelectAvatarEvent?) with a property for name/id and dispatch it from View1 when the link is clicked. In the Application add an event listener for this custom event, and catch it, change the view index to View2 and create a function/property in View2 that you can pass the string/event to. Depending on how it is implemented, might need to account for delayed instantiation of View2.
